FORD FREESTAR DOOR PROBLEM

my freestar the ABS light and brake light come on the speedo stops working the odometer shows dash dash etc. The trans ax light blinks the interoit light won, t work when you open the door. The automatic door locks don, t lock when all this goes on. This comes and goes at will also I can, t locate a shop manual for this van like haynes or chiltons.

The vehicle needs a speed sensor. It should be on the output side of the transmission on the freestar. I believe it is located on the passenger side. Have a dealer look up the part and they can give you a printout of where it is located.
